There are essentially two types of business contracts: oral and written. Quite often for regular business transactions and short-term projects, an oral contract will suffice. In all such cases, an oral contract is deemed as valid as a written contract. An oral contract is also admissible in courts of law, but because of its very nature, it could be subject to infirmities and it can be difficult to establish the truth in courts.
Written contracts are much safer and any breach by either party can be well established in law courts. Written contracts are made out on paper or in this computer age, they are also created electronically. Lawyers are happier arguing in courts based on a written business contract rather than an oral contract because it is much easier for the courts to uphold the disputant’s claims when things are unambiguously written down on paper.
